Carbon steel blade is corrosion protected with oil. The oil must be carefully removed before any use with grocery. Blade must be cleaned and dried after every use. We recommend using oil for corrosion protection. If the knife is left wet inside the sheath, it will get black markings and even rust. If you use knife with foodstuff, use eatable oil for example sunflower or rapeseed oil. Olive oil may be too acidic and affect marks on blade.

The kitchen and fish knives as well as the Game knife are made of stainless steel, which does not require oiling.

The cubs’ imagination really took over, when they began to hear a constant pounding from the factory. It was like an iron giant’s sledgehammer banging.
